Earlier today, the Web was in a tizzy over a wacky political ad for GOP presidential candidate Herman Cain that showed his campaign manager smoking.

But Cain has got nothing on San Francisco Mayor Ed Lee, whose newest campaign ad (not sponsored by the mayor) in­cred­ibly features rapper M.C. Hammer, Twitter co-founder Biz Stone, Giants closer Brian Wilson, Black Eyed Pea Will.i.am, and former Mayor Willie Brown all rapping Hammer’s hit “2 Legit 2 Quit.”

At the center of the ad is Lee’s prominent painter’s brush mustache, as the celebrities sing “Fear the Mustache!”, a nod to Wilson’s trademark slogan, “Fear the Beard.

But these high-profile San Franciscans aren’t just playing around.

The handiwork of an independent group called San Franciscans for Jobs and Good Government, the campaign ad comes on the heels of accusations leveled at Lee's campaign that he was involved with voter fraud in Chinatown.

The group says it made the ad because Lee has as mayor backed growth and job creation for technology companies, the San Francisco Chronicle reports.

Biz Stone has also shown Silicon Valley’s support for the mayor before, accidentally sending out a flood of spamming tweets endorsing Lee earlier this month.

But this star-packed and inexpensive ad — costing just $18,000 to make — may be far more effective than Stone’s tweets, especially when the harem pants back in action. Watch the ad below:
